TT system, have upfront 60947-2 with added on 61008 with mA and ms settings, now I’m getting Zdb of 22.9 ohms and Ka of 4.0, now the RCD can be what ever I set it to but I’m struggling, I’ve set it to 300ma and 300ms but can’t seem to get it to trip? I also have a split phase supply so have L1 and L3 and N but can’t trip on either phase thanks
